Comment (by klaussfreire):

 Sorry for the silence, the assertion error has been fixed already. Some
 bug I couldn't find with encode_window_bands_info, but I just made anmr
 use the other (codebook_trellis_rate? something like that) which is very
 similar but better (avoids adding holes or picking a codebook that cannot
 encode the coefficients, for instance).

 I'm currently doing a frankenstein between v9 and v7, to get v9 close to
 v7 in stability only with better quality. I'm close to posting v9b,
 hopefully a version that can be sliced and committed (if v7 was acceptable
 v9b should be as well)
